refactor: Separate AIModel from Chat (#123)
* Separate AIModel and Chat - remove Backend field from Chat as it is contained in the AIModel * Remove WithModel(AIModel) and WithModel<TModel> WithModel(AIModel) and WithModel<TModel> makes more questions than answers. It gives user one clear workflow. Add this flow with register as an example." * Make use of the ChatId property of the Agent * Use const modelIDs instead of magic strings in the predefined models * Fix AgentService.Restart() * Fix orphaned culumn in databases * Fix copy paste bug in SqliteChatRepository.cs * Fix noninformative error thrown when modelId is not found * Standarize AgentContext like ChatContext - examples use const model ids instead of magic strings - add flux id (the approach in examples will be refactored) * Minor changes to satisfy rebase.
